Tetrabenzo[a,d,j,m]coronene (TBC) is a contorted polyaromatic molecule which shows near co-facial π–π stacking in the crystalline state and the high electronic coupling resulting from the packing renders it a potential candidate as a transistor material. Substitution at the periphery perturbs the packing due to steric as well as dipolar interactions and thus changes the electronic coupling between
